Dịch bài đọc:

Nước có tầm quan trọng sống còn đối với mọi sinh vật. Không có nó, tất cả các sinh vật sống chắc chắn sẽ chết. Chúng ta cũng sử dụng một lượng nước lớn hàng ngày trong nhà, trong các nhà máy và trong các nhà máy điện. Hầu hết nước này là nước ngọt và nó đến với chúng ta từ các hồ chứa, sông hồ.

Bề mặt Trái đất được bao phủ bởi những vùng nước rộng lớn mà chúng ta gọi là đại dương và biển. Nếu bạn đã nếm nước từ biển, bạn sẽ biết rằng, không giống như nước ngọt, nước biển có vị mặn. Điều này là do sự hiện diện của natri clorua đến từ đất. Sông mang nó ra biển.

Mặc dù cả nước mặn và nước ngọt đều không có màu gì, biển thường có màu xanh dưới ánh sáng mặt trời. Lý do là ánh sáng mặt trời được tạo thành từ nhiều màu sắc. Một số màu biến mất nhanh chóng trên biển nhưng ánh sáng xanh bị dội ngược lại hoặc bị phản xạ, lên bề mặt. Điều này làm cho biển trông xanh.

Vấn đề 8. Một container có hình khối có kích thước như trong hình. Các thùng có 54 lít nước trong đó. Bình muốn biết một xô đầy chứa bao nhiêu lít nước , do đó, ông đổ cả xô nước vào container và thấy rằng mức độ của nước tại 7 8 là chiều cao của container. Từ đó, ông có thể tính toán bao nhiêu lít nước một xô đầy chứa . Nếu container rỗng , bao nhiêu xô nước phải Bình đổ vào các container để làm cho nó đầy đủ?

To solve this problem, let's break it down step by step.

Step 1: Calculate the volume of the cuboid container.
The volume of a cuboid is given by the formula:
Volume = Length × Width × Height

Given:
Length = 12 meters
Width = 6 meters
Height = 4 meters

Volume = 12 × 6 × 4 = 288 cubic meters

Step 2: Convert the volume to liters.
Since 1 cubic meter = 1000 liters, we have:
Volume = 288 × 1000 = 288,000 liters

Step 3: Determine the volume of water after pouring a full bucket.
The water level after pouring the bucket is at 7/8 the height of the container, which means the volume of water is 7/8 of the volume of the container.

Volume of water = (7/8) × 288,000 liters = 252,000 liters

Step 4: Calculate the volume of water in one bucket.
Since initially, there were 54 liters in the container and after pouring the bucket, there were 252,000 liters, the volume of water in one bucket can be found by subtracting the initial volume from the final volume.

Volume of water in one bucket = 252,000 liters - 54 liters = 251,946 liters

Step 5: Determine how many buckets are needed to fill the container.
To find out how many buckets are needed to fill the container, divide the volume of the container by the volume of water in one bucket.

Number of buckets needed = 288,000 liters / 251,946 liters ≈ 1.144

Since Bình cannot pour a fraction of a bucket, he would need to pour 2 buckets of water to fill the container completely.
